Forbidden relationship questions for my story

One of the plot points in my story is that two people who come from two different kingdoms get together and have a child. This is forbidden, but it wasn't at the time it happened. I know this has already been done a thousand times before, but I want to go about it a little differently. Now the questions I have for you are this:

Should the couple meet and fall in love, or should one take advantage of the other? Or should it be a decision made without any thought and something they both regret?

Which social standpoint would create the most drama:

1) The father and mother are leaders of their respective kingdoms,

2) One is a leader and the other a peasant (if so, which one),

3) Both are middle class, but well respected

And finally: The mother is going to keep the child in her kingdom, but she won't tell anyone about his parentage until much later, when the child is grown. But what about the father? Should he know but not care, or not know at all? When he does find out, should he hate the child, or love him but pretend not to? Keep in mind, by the time the truth gets out, both the mother and the father will be married to someone of their kingdom.

You don't have to answer all the questions at once, but you can if you want. I'd like you to answer at least one or two. And please no "It's your story so do whatever you want". I don't KNOW what I want, that's why I'm asking XD

I would say it's their own choice (if one takes advantage of the other that's rape and like…. Rape isn't good and that would have bad memories for the victim prob, and if it was the mom, then like…. That adds a whole other set of problems to the parentage), but it wasn't love at first sight.
And I like options 2 and 3…. 2 makes it a bit Disney…. Like Cinderella or something lol.
But it doesn't HAVE to be fairy tale esque.

I believe the conception of the child should be consented to by both parties. If one takes advantage of the other, your painting a poor view of the kingdom they come from early on. (Unless that's your goal) If you go the direction of them regretting the decision, then your main character would definitely have some emotional issues being born out of shame. Out of the three plot prompts you've shared, I think I personally would go this route: Both man and woman are peasants, but one of them gets married into the royal family, if her perhaps by her beauty, if the him, maybe he saved a runaway carriage with the princess inside. Either way, I would start them off as equals, then divide them in status. With a royal parent in one kingdom, and a peasant in another, it expands the setting of the story, and intensifies the fact that the main characters very existence breaks the law, one of his parent's has to uphold. If you leave the father in the dark, it allows his realization to be a key plot point in your story. Perhaps he's always wanted a son/daughter, but could never conceive one with his current wife, and now he finds out he has a fully grown child (the gender he wanted) from a night of passion he's never forgotten. Maybe towards the end of the story reunite the parents in a platonic way for a common goal. I wouldn't romantically reunite them, but it would bring closure to the audience to see they don't hate each other like typical one night stands, or ex's.
